Description

- Heat up oven to about 200°C

- Put some PLA scraps on your metal plate (I like to use a metal plate instead of the baking tray because it is flat and not coated with anything like Teflon or similar. I got mine from a local metal shop, just measure the size of your baking tray and give them the correct dimensions. Mine is 4mm aluminum and did cost me 5Euros.) Don't use too much PLA, it is easy to add more later. Now put everything in the oven.

- I wanted my PLA to be nice and flat so I let it bake in the oven for 30 minutes.

- You will get some air bubbles, depending about the shape of your scraps and the amount of infill. I didn't want to have any bubbles in my lamp, so you could possible wait for hours and hours until all the bubble pop and the PLA melts together. But with a small blowtorch it is much easier to pop the bubbles. Just heat up the surface gently and all the bubble pop instant. Just don't overdue it, you will burn the plastic. Better take several passes.

- Another 10 minutes in the oven so that all the holes melt together. If you still have bubbles you can repeat this process as often as you want.

- Let everything cool down.

- Remove the plastic from the metal plate. If your plastic is stuck really well, try putting it in the freezer for several minutes. The plastic will shrink a bit and you can start peeling the corners of. Some thin liquid like IPA works also really well. Just take your time and be careful. The thin PLA is quite brittle (learned it the hard way by dropping it on a concrete floor and breaking some pieces).

- build a shallow wooden box (or print one) a bit smaller than your PLA piece. I painted mine white to match with the wallpaper.

- Cut the led stripe in fitting pieces and add as many as you like. More LEDs equals to more light.

- Solder all LEDs together and try them out. Now hold your piece roughly 1cm over your wooden box and give it a try. Too much or to less light? Adjust the height of your PLA Panel. I found 1cm to be about right for mine.

- I put one nail in each corner of my light box (screws or something similar would also work well) so that the nail head was 1cm above the box.

- I added some glue to the nail heads and glue my PLA piece in place.

- Put something in the back to hang or stand up your lamp and enjoy.

Tip: Transparent PLA works best, but I like the combination of transparent and nontransparent materials.

Tip: If you want to sand the plastic you will get a dull surface. If you want to avoid that you need to sand to a pretty high grid like 5000 or more. Wet sandig gives the best result.
